HYDRANT AND FAUCET.

SPECIFICATION forming part of Letters Patent No. 502,349, dated August1, 1893.

Application led April 19, 1892. Serial No. 429,706. (No model.)

To all whom it may concern,.-

Be it known that I, WILLIAM B. CoRNoG, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Hydrants and Faucets Therefor, of which the following isa specification.

The object of my invention is to construct an outside water supplydevice, commonly called a hydrant, in such a manner as to obviate thedrip or waste under-ground or in a cellar, and so construct the valvemechanism that it will be non-freezable.

A further object of my invention is to provide a hydrant with aweather-proof metallic packing case.

It will be understood in the outset that my invention is not onlyapplicable to standf ing hydrants, but also to what are termed summerhydrants, that is, hydrants which project from the wall of the building.The former hydrants are generally arranged with the valve mechanismburied in the ground below freezing point. Consequently in order preventthe water in the stand pipe freezing, the valve is provided with a wasteoutlet, and the water from the stand pipe, when the valve is turned off,escapes into the ground, and as the stand pipes generally contain abouta pint of water, it will be readily understood that the water escapingwill soon make the ground around the hydrant damp and soggy, and inorder to repair the valve of this hydrant, the surrounding ground has tobe dug up. This is not only objectionable on account of the expense, butalso in the fact thatf the yard pavements are in most cases cement, anda break in a cement pavement can never be repaired to make the pavementthe same as it originally Was. The valves in the summer hydrants asusually constructed, readily freeze, and these summer hydrants are objectionable on this ground.

In the accompanying drawingsz--Figure l, is a sectional view of myimproved hydrant. Fig. 2, is a sectional planview on the line 1-2, Fig.l, drawn to an enlarged scale. Fig. 3, is a sectional perspective viewof the hydrant. Fig. 4, is a view of sufficient of a summer hydrant orwall outlet to illustrate my inven` tion.

I will first describe my invention, referring particularly to Figs. l, 2and 3, in which A is a sheet metal body preferably Iiuted, and eitherriveted or welded, resembling the ordinary wooden hydrant. The body A ismounted on a base B, preferably of cast metal, the base having a fiangeb over which the bodyA is placed. This body is secured to the flange inany suitable manner. Secured to the base is the wooden ground structureC,shaped the same as the base of an ordinary wooden hydrant. Thisstructure passes inside of the base B and rests against a flange b asclearly shown in Fig. l, and is secured to the base in the presentinstance by staples c. It will be understood however, that otherfastening means may be employed without departing from my invention. Thecap a of the hydrant is made inthe present instance of met-al, and isdetachably secured to the body in order that it may be readily removedso that access may be had to the cut-oft' valve when To the face of thehydrant is secured a face plate a into which is screwed the faucet D.The water suppl y pipe E passes up through the center of the hydrant,and is provided with a T e at its lower end to one end of which can beattached the inlet pipe, the other branch being provided with a plug.

At the upper end of the pipe E, I preferably mount a Vcut-off Valve Ffor cutting off the [supply of water to the faucet when repairs arenecessary; the faucet can then be removed bodily Without cutting off thesupply from This valve F however, is not formed an L-couplingf intowhich the screw threaded portion d of the faucet D is attached. Thescrew threaded portion d is screwed into the face plate a. and it willbe noticed on referring to the drawings that the portion d is smallerthan the portion d of the faucet, so that the portion d will readilypass through the opening in the face plate A, and the two threads beingof the same pitch the faucet can be readily screwed intoplace. Iso arrange it that the threaded portion d is some what longer than thethreaded portion cl, so that this latter threaded portion will seatitself forming a water tight joint, as a water ing through which passesthe crank t' of the stern I, which is provided with a suitable handle ilfor opening and closing the valve.

In Fig. 4,I have illustrated what is termed as a summer hydrant, that isa hydrant which simply consists of a stand pipe on the inside wall of abuilding, and having an eX- tension which passes through the wall, towhich is secured the faucet, but these hydrants as usually made, freezereadily and are therefore objectionable. The hydrant shown in Fig. 4, ismade in the same as heretofore with the exception that the valve is notexposed to the atmosphere. The valve casing D being simply extendedpreferably of a length sufficient to carry the valve and its seat backto the inner side of the wall, the face plate a to which the faucet issecured, being mounted on a suitable splash board.

Turning again to Figs. 5 and 6, I would describe particularly theconstruction of the faucet by which the water at the valve is preventedfrom freezing. In the ordinary construction of a faucet, the air thatwould enter through a nozzle would be sufficient to freeze the wateraround and back of the valve, notwithstanding the fact that the valvewas mounted in a packed casing, and the main object of my invention isto prevent this freezing of the water at the valve. As shown in Fig. 1,the hydrant is packed with sawdust or other non-conducting material, andin Fig. 4, the supply pipe is arranged at the inside of the wall. Thefaucet stem is of a suiicient length to couple to the stand pipecoupling, and the valve stem is of a corresponding length, the valvebeing mounted on the end of the stem, so that it is atacentral point inthe body of the hydrant shown in Fig. l, surrounded by packing; and atthe inner side of the wall shown in Fig. 4. On. the valve stem is an aircheck m, which is simply an enlargement in the form of a piston, and isnear the forward end of the stem. This air check passes into the reducedportion d2 of the faucet casing, as shown in Fig.' 6, thus checking thefree flow of air through the casing to the water valve h. In the reducedportion d2 is a groove cl3 to allow the entrapped water between the aircheck and the water valve to escape through the nozzle, but this openingis not sufficient to allow the cold air to materially affect the waterback of the valve h. In some instances I may use two or more air checkswithout departing from my invention,

and I preferito use two checks when the casing is long as shown in Fig.4. Thus by the arrangement of a piston check, the valve 7L will alwayscome to its seat, o wing to the fact that the piston check m slideswithin the reduced portion d2, and does not seat against it. Thus by theabove construction I am enabled to make a non-freezable hydrant eitherof the standing type or of the wall type, the former having a stand pipeincased within packing, the water valve being at the upper end of thestand pipe near the nozzle, but in the cen- Yter of the packing, thuspreventing'waste,

and obviating the necessity of digging up the hydrant when the valve isto be repaired. The faucet can be removed by simply unserewing it fromthe casing and stand pipe and after it has been repaired the faucet canbe coupled without disturbing the body portion of the hydrant. a hydrantof this construction is about the same as the cost of an ordinary woodenhydrant.

It will be understood that the valve need not necessarily be of theFuller type, but any valve may be used providing an air check is placedbetween it and the mouth of the nozzle.

I claimlas my invention- 1. The combination in an outside water supplydevice, of the faucet casing, the water valve, an air check valvebetween the water valve and the nozzle of the faucet, and means forpermitting the drainage of water from the space between said valves,substantially as described.

2. The combination of -the faucet casing, the valve stem having a watervalve at one end, and provided with an air check valve adapted to fitinto a flanged portion on the interior of the faucet casing between thewater valve and the nozzle, and means for permitting the drainage ofwater from the space between the two valves, substantially as described.

3. The combination of the faucet casing, the valve stem and water valvethereon, piston air check carried by said valve stem, an internal flangeon the faucet casing into which the piston air check moves, with a dripopening in the internal flange to allow the entrapped water between theair check and the water valve to escape, substantially as described.

4. In a hydrant structure, the combination of the sheet-metal body, acast metal base upon which the body is mounted, withY a wooden groundstructure secured to the base, and a supplypipe and valve, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
